Application filed July 29, 1913.

durable in construction, ellicient and relia is in operation and adapted for ready assemoly or disinounting.

Another object of my invention is to provide a soldering-iron embodying a readily renewable heater and a removable working .iemher or tip provided with means for pre venting any likelihood of damage during the process of repointing, etc.

In the older types of electric soldering irons many defects and disadvantages may be found. The first cost is hi gh and no provision is made for the renewal of the heater; the weight is excessive and not properly halanccd' by reason of the iron cylinder employed with the heating element; the copper tip, although renewable, is of a form easily damaged and facilities for cleaning the iron are not provided; and many irons embody theaded joints, which are unsuitable for employment in appa "atus of this class, by reason of the possibility of destruction through the combined action of heat and acid fumes.

i iccording to my present invention, 1 pro vide an electric soldering-iron or the like embodying means which singly or collectively obviate the above-mentioned disadvantageous features.

he novel and advantageous features residing in my invention will he more clearly brought out in the description thereof and in the accompanying drawing, in which Figure l is a. view in longitudinal section of a soldering-ironconstructed in accordance with my invention, Fig. 2 is a View thereof in end elevation, Fig. 3 is a sectional View on the line IIIIH of Fig. 1, Figs. i and 6 are sectional views of modifications of portions of the device shown in Fig. 1, Fig.

The conical heater may he of any suitable type. Preferably conducting element 10 is wound in the grooves of a fluted conical spool 11 and then smoothly covered with a suitable electrically-insulating and heat-conducting cement. Th handle lot any suitable form is provided with an inwardly-extemiing annular flange 13 for co- Q0 operation with the member 5, as hereinafter described. The intermediate expansihle member 5 comprises two oppositely-disposed and approximately semi-cylindrical perforated shells it provided with outwardly-extendingend flanges 15 that are. respectively adapted to expansihly engage the flange 9 of the tip 2 and the flange 13 of the handle l. The split expansihle member 5 is forced into operative eng: geinent with the flanges and 13 by an adjustable screw 16 that engages oppositely disposed similar segmental open ings 17 in each of the perforated shells ll. A plurality of supply conductors 18 extend through the handle l and the member 5 to a plurality of suitably disposed terminal menihers 19, to which the ends of the conducting element 10 are suitably secured.

It will be seen that, in the structure above described, very little radiated heat from the "lClBii-f of the lismile l i -m the supply conducl'i .sipated through the member 5.
